To quantify potential bridging of HIV transmission between the injection drug using subpopulation to the non-injection drug using population through unprotected heterosexual sex.
Secondary analysis of cross-sectional data.
A sub-sample of participants who reported having a permanent partner who are not injection drug users and have not injected drugs in the past (N=1379) was selected from a survey implemented in 26 Ukrainian cities in 2011. This study evaluates the association between consistent condom use and awareness of HIV status as measured by rapid testing during the study (known/unknown HIV+, known/unknown HIV- and undetermined) among a sub-sample of male injection drug users (IDUs) who have a non-injecting permanent partner. Poisson regression, with robust variance estimates, was utilized to identify associations while adjusting for other factors.
Reported consistent condom use varied between 15.5% (unknown HIV-) and 37.5% (known HIV+); average use was 19.3%. In multivariate analysis, males who were aware of their HIV+ status were more likely to report recent consistent condom use compared to those who were unaware of their HIV+ status. This association remains after adjustment for age, region, education level, years of injection, alcohol use, self-reported primary drug use and being an NGO client (prevalence ratio=1.65; 95% CI 1.03-2.64). No such association was found for those who were HIV-.
Our results regarding HIV-positive male IDUs reinforce previous findings that HIV testing and counselling may be an effective means of secondary prevention. Further research is needed to understand how to effectively promote safer sex behaviours for IDUs who are currently HIV-.
量化通过无保护异性性行为,注射吸毒亚人群与非注射吸毒人群之间潜在的HIV传播桥梁作用。
横断面数据的二次分析。
从2011年在乌克兰26个城市开展的一项调查中,选取报告有非注射吸毒且过去未注射过毒品的固定性伴侣的参与者子样本(N = 1379)。本研究评估在有非注射固定性伴侣的男性注射吸毒者(IDU)子样本中,研究期间通过快速检测衡量的坚持使用避孕套与HIV感染状况知晓情况(已知/未知HIV阳性、已知/未知HIV阴性及未确定)之间的关联。采用具有稳健方差估计的泊松回归来确定关联,同时对其他因素进行调整。
报告的坚持使用避孕套比例在15.5%(未知HIV阴性)至37.5%(已知HIV阳性)之间;平均使用率为19.3%。在多变量分析中,知晓自己HIV阳性状态的男性与不知晓自己HIV阳性状态的男性相比,更有可能报告近期坚持使用避孕套。在对年龄、地区、教育水平、注射年限、饮酒情况、自我报告的主要毒品使用情况及是否为非政府组织服务对象进行调整后,这种关联仍然存在(患病率比值 = 1.65;95%置信区间1.03 - 2.64)。对于HIV阴性者,未发现此类关联。
我们关于HIV阳性男性注射吸毒者的研究结果强化了先前的发现,即HIV检测和咨询可能是二级预防的有效手段。需要进一步研究以了解如何有效促进目前HIV阴性的注射吸毒者采取更安全性行为。
